Hi,

Hi,

I am working on ArcObjects using Visual Studio 2015.  I am connecting 'sql server' connection and getting System.NullREferenceExpceiotn occureed in MyToolbox.dll. I am using ArcMap 10.6.1.

 Here are steps

1. Added App.config 

<add name="SQLserver" connectionString="server=xxx;database=xxx;User Id=xxx;Password=xxx"/>

2.  Button.vb file

Dim SqlDB As Object = ConfigurationManager.ConnectionStrings("SQLserver").ConnectionString

Note: I am able to connect with same credentials as desktop application but it doesn't working as a dll file. Do I require a difference method. 

Thanks a lot

Rani

Where you add the line? You must place it in connectionstrings section

Thanks for your response. I am using under connectionstrings. Any other reason it is breaking?
